What has been your experience in signaling holds to the PSTN?  The more everyone converts to SIP and peers with our carriers, the more stacks we see on the far end.  A growing number seem to have trouble accepting any kind of hold SDP signals such as a=inactive/sendonly, quad zeros, etc.

Is this vexing you too, or is it just me?
